What changes were proposed in this pull request?
This is a followup PR for #30573 .
After this change applied, stage memory metrics will be updated on stage end.
Why are the changes needed?
After #30573, executor memory metrics is updated on stage end but stage memory metrics is not updated.
It's better to update both metrics like
updateStageLevelPeakExecutorMetricsdoes.Does this PR introduce any user-facing change?
Yes. stage memory metrics is updated more accurately.
How was this patch tested?
After I run a job and visited
/api/v1/<appid>/stages, I confirmedpeakExecutorMemorymetrics is shown even though the life time of each stage is very short .I also modify the json files for
HistoryServerSuite.
